It depends on how old your furnace is and the cost to get a new furnace. A good rule of thumb is, no matter the age of the furnace, if the cost to repair is 50% of the cost of a new furnace, you should replace it. But for less expensive repairs, you should be less resistant to replacing the furnace the older it is. So if the furnace is 20 years old, and the cost to repair the furnace is only 10% of the cost of a new furnace, you should probably replace it (because itâs more likely to break down again soon).
Do the Math. If you replace your furnace with a 97% efficient system (look for an Energy Star furnace or A/C system and compare the AFUE and BTU levels), then you would cut your heating bills to around 20%.To see if it's worth spending the money, add up your fuel bills for last winter,then multiply that sum by 20%.o the Math. If you replace your furnace with a 97% efficient system (look for an Energy Star furnace or A/C system and compare the AFUE and BTU levels), then you would cut your heating bills to around 20%.
